8 Claims.

My invention relates to an improved gluing machine mounted on an elevated frame by means of which certain types of telescope boxes can be glued and set up by the customer or packer of 1 tion and arrangement. I attain these and other objects of my invention'by the mechanism illustrated in the accompanying drawings, in Which Figure l is a perspective view of the entire machine;

Fig. 2 is a perspective view of a portion of the machine showing the cans of glue in their inverted position, with a portion of the frame and. of the spouts of the cans broken away;

Fig. 3 is a side elevation of one of the cans with its spout;

Fig. 4 is a rear elevation of same;

Fig. 5 is a vertical section throughva portion of the spout and the discharge nozzle;

Fig. 6 is an end view of cap 4;

Fig. 7 is a detail View partly in side elevation and partly in section of cap 6 and washer 1;

Fig. 8 is an end elevation of bars I I and 20, showing the contour of slot I9;

Fig. 9 is a detail View of wing nut and bolt 22;

Fig. 10 is a detail View of screen 5;

Fig. 11 is a section of a portion of the top of can 8 and cap 9 and washer valve 23; and

Fig. 12 is a detail view of washer 23.

Like numerals designate like parts in each of the several views.

Referring to the accompanying drawings, I provide a plurality of cans 8 for containing glue. Each can has a spout I to the lower end of which is attached an elbow 2. A nipple 3 is threaded on elbow 2. Nipple 3 is also threaded for engagement by a cap.

For distributing the glue I provide an apertured cap 4 which is screw threaded on the end of nipple 3 and which thereby holds the several screens 5 in place against the end of nipple 3 as shown in Fig.5, and through which the glue is fed by gravity. I also provide a cap 6 which has no aperture but does have a washer 'I, and which may be used to replace cap 4 and screens 5 when'the cans are not in use, to prevent evaporation of the glue. 1 Can 8 has asuitable cover 9. This cover has an opening 2I as shown in Fig. 11. A leather or chamois disk is mounted in cover 9. This disk 5- 23 has ahalf moon slot 24, as shown in Fig. 12, which functions as an air valve.

As shown in Fig. 1, cans 8 rest on an upper bar I I. A lower bar 20 extends parallel with and is attached to bar H. Bar II has aprojecting 10 end I 2. of suitable size to seat in the slot. I3 of the elevated horizontal'end framemember'lfl'. Member I4.is aiiixed to and supported in 'itselevated position by post I5, which in turn is affixed to base I6. A brace I1 is fastened to base 15 I6, post I 5 and frame member-I 4 to securely brace these members to eachotlier, as shown in Fig.1. As shown inFigs. 1 and 2, I provide suitable? pivots I8 by means of which bars II and are pivotally mounted on members I4.

The brackets I0 engage the spouts I which are welded to the glue cans 8, and also carry the bolts 22, the heads of which are slidable in the longitudinal slot I9 in bars II and 2D. The wing nuts on bolts 22 permit of tightening them 25 in an adjusted position, so thatthe cans 8 can be readily fastened in whatever spaced position is desired according to the size of the box which is to be glued by the machine. The cans 8 are filled through the openings covered by the covers 9, and the glue is fed by gravity through the spouts I, elbows 2 and nipples 3 to and through the screens 5 and the aperture in cap 4- Flaps.

of the folding boxes to be glued are brought underneath to the caps 4 and lightly placed on end of cap 4 which applies the glue.

If the operator should find it necessary to stop gluing, all that need be done is to invert the glue cans and the bars H and 20 on which they rest and to which they are adjustably attached,

as these bars are swingably mounted on the end frame members I4 by the pivots I8. The glue will automatically quit feeding and flow back into the cans by gravity. After the operator is through using the machine he may remove the 5 cap 4 and screens 5 and replace them with the cap 6 which has no aperture, in order to keep the glue from evaporating.

As shown in Figs. 11 and 12, the disk 23 has a half moon slot 24 cut in it. The action of this is like a valve, inasmuch as when the can is in operating position air will pass through the hole 2I in cover 9 and the suction from the liquid in can 8 pulls the air through 24. Then when the can is tilted inasmuch as disk 23 is placed against the top, the aperture formed by slit 24 automatically closes, keeping the glue from spilling.

What I claim is: s I

1. In a gluing machine,thecombination of a frame, bars pivotally mounted on the frame, a plurality of cans adjustably mounted on the bars, spouts on the cans, horizontally disposed nipples on said spouts, apertured caps on the nipples, and screens contained within the caps.

2. In a gluing machine, the, combination of a frame, including elevated frame members having slots in their upper portions, bars pivotally mounted on said frame members, one of said bars having projecting ends seatable in said slots, cans adjustably mounted on the bars,

spouts on the cans, horizontally disposed nipples on said spouts, apertured caps on-the nipples, and screens contained within the caps.

3. In a gluing machine, the combination of a frame, including elevated frame members having slots in their upper. portions, bars pivotally mounted on said frame members, one of said bars having projecting ends seatable in said slots, cans mounted on the bars, spouts on the cans, horizontally disposed .nipples on said spouts, apertured caps on the nipples, and screens contained within the caps.

4. In a gluing machine, the combination of a frame, a pair of bars secured to each'other and pivotally mounted on the frame, said bars having a longitudinal slot, cans seated onthe bar, spouts on the cans, brackets attached to the spouts, bolts and wing nuts engagingfsaid brackets, said bolts having their heads slidably mounted on the longitudinal slot in the bars for securing the cans in an adjustable positionjon the bars, the aforesaid spouts terminating in horizontal nipples for the discharge ofglue.

5. In a gluing machine, the combination of a frame, a pair of bars secured to each other and pivotally mounted on the frame, said bars having a longitudinal slot, cans seated on the bar, spouts on the cans, brackets attached to the spouts, bolts and wing nuts engaging said brackets, said bolts having their heads slidably mounted on the longitudinal slot in the bars forsecuring the cans in an adjustable position on the bars, the aforesaid spouts terminating in hori- ,in the caps.

6. In a gluing machine, the combination of a supporting frame, bars pivotally mounted on the frame, cans for containing glue mounted on the bars, spouts depending from said cans, covers onthe cans, said covers having apertures,,fiexible discs contained within the covers, said flexible discs having arcuate slots whereby the discs will function as air valves substantially as described. I

7. In a gluing machinathe combination of a base, posts afiixed to the base, horizontal-frame members mounted on the upper ends of the posts, said frame members having slots, bars pivotally mounted on the horizontal frame members, said bars having projecting ends seatable in the slots of the frame members, cans secured to the bars, said cans having spouts terminating in horizontal nipples for the discharge of glue.

8. In combination with the apparatus defined in claim '7, means for securing the cans in any desired laterally adjusted position on the aforesaid bars.
